                 Fair Isaac Announces First Quarter 2007 Results

                        Total revenue of $208.2 million;
                           Earnings per share of $0.52



    MINNEAPOLIS--(BUSINESS WIRE)--Jan. 24, 2007--Fair Isaac
Corporation (NYSE:FIC), the leading provider of analytics and decision
technology, today announced the financial results for its first
quarter ended December 31, 2006.

    First Quarter Fiscal 2007 Results

    The company reported first quarter revenues of $208.2 million in
fiscal 2007 versus $202.8 million reported in the prior year period.
Net income for the first quarter of fiscal 2007 totaled $31.2 million,
or $0.52 per diluted share, versus $28.5 million, or $0.43 per diluted
share, reported in the prior year period. First quarter fiscal 2007
results included a $2.3 million tax benefit arising from adjustments
to income tax reserves resulting from the conclusion of a tax audit
and the extension of the Federal Research Tax Credit.

    "We are pleased with our operating results, earnings per share,
and cash flows for the quarter, and appreciate the hard work of our
employees in good expense management," said Charles M. Osborne, Fair
Isaac's interim chief executive officer. "We are still not satisfied
with our rate of revenue growth. The expected benefits from our change
to the Integrated Client Network organization have been slower than
anticipated as people settle into new roles within the structure. We
remain steadfast that our vision provides long-term growth for our
customers, shareholders and employees."

    First Quarter Fiscal 2007 Revenues Highlights

    Revenues for first quarter fiscal 2007 across each of the
company's four operating segments were as follows:

    --  Strategy Machine(R) Solutions revenues were $110.7 million in
        the first quarter compared to $112.0 million in the prior year
        quarter, or a decrease of 1.2%, primarily due to a decline
        associated with mortgage, originations, and precision
        marketing products offset by an increase in revenues from
        fraud, customer management, and collections and recovery
        solutions.

    --  Scoring Solutions revenues were $44.9 million in the first
        quarter compared to $46.2 million in the prior year quarter,
        or a decrease of 2.7%, primarily due to a decrease in revenues
        derived from our PreScore(R) Service.

    --  Professional Services revenues increased to $38.4 million in
        the first quarter from $32.8 million in the prior year
        quarter, or by 17.0%, primarily due to an increase in revenues
        from analytics, fraud, and customer management consulting
        offset by a decline associated with collections and recovery
        implementation solutions.

    --  Analytic Software Tools revenues increased to $14.2 million in
        the first quarter compared to $11.8 million in the prior year
        quarter, or by 20.4%, due to an increase in revenues generated
        from sales of the Blaze Advisor(TM) product.

    Bookings Highlights

    The bookings for the first quarter were $72.1 million versus
$127.8 million in the same period last year. The company defines a
"new booking" as estimated future contractual revenues, including
agreements with perpetual, multi-year and annual terms. Management
regards the volume of new bookings achieved as one indicator of future
revenues, but they are not comparable to, nor should they be
substituted for, an analysis of the company's revenues.

    "Our lower level of bookings this quarter reflects our emphasis on
license and service sales," stated Mr. Osborne, "and these tend to
carry a lower booking value."

    Balance Sheet and Cash Flow Highlights

    Cash and cash equivalents, and marketable security investments
were $271.7 million at December 31, 2006, as compared to $267.8
million at September 30, 2006. Significant changes in cash and cash
equivalents from September 30, 2006 include cash provided by
operations of $59.6 million, borrowings under the revolving credit
facility of $70.0 million, and $30.8 million received from the
exercise of stock options and stock issued under an employee stock
purchase plan. Cash used during the first quarter of fiscal 2007
includes $5.1 million related to purchases of property and equipment
and $154.5 million to repurchase common stock.

    Outlook

    The company expects revenues for second quarter fiscal 2007 of
approximately $215.0 million and earnings per diluted share to be
approximately $0.48. The company expects revenues for fiscal 2007 of
approximately $870.0 million and earnings per diluted share to be
approximately $2.15.

    Organizational Announcement

    The company also announced today that Andrew Cecere has stepped
down as a board member, effective immediately, in order to devote more
time to his new role at U.S. Bancorp. Mr. Cecere, who has been a board
member since April 2004, was recently named vice chairman and chief
financial officer of U.S. Bancorp, where he had previously served as
vice chairman of wealth management.

    "I want to extend my thanks to Andy for his contributions to Fair
Isaac Corporation," said A. George Battle, chairman. "We are sorry to
see him go, but all of us at Fair Isaac wish him well in his new
position at U.S. Bancorp."

    Company to Host Conference Call

    The company will host a conference call today at 5:00 p.m. Eastern
Time (4:00 p.m. Central Time/2:00 p.m. Pacific Time) to discuss its
first quarter fiscal 2007 results, and outlook for fiscal 2007. The
